I spend months building up my stamina physically and chakra wise doing exercises like running, weight lifting, and moving objects and things with pure chakra. I spend a few more months learning extreme chakra control. As is my heritage as a Hyuuga I must have precise chakra control. I spend several months on this, practicing each day for endless hours on moving my chakra to all parts of my body, even a small part such as a toe or finger. I progress over the years, keeping myself in fit conditions. Without being around people I've had more time to train and practice. The end of one year has come and my strength and speed are tripled that of the regular Academy Students in the distant villages, due to the fact that I was secluded with nothing else to do but train. I now seek to test my skills on a village genin to see if I match their level of skill.
